Pr E2F0014-19-33 el ar in im This version: Mar. 1999 MSM9562 Previous version: Oct. 1998 IC for FM Multiplex Data Demodulation GENERAL DESCRIPTION The MSM9562 is an IC which demodulates FM character multiplex signals in the DARC (Data Radio Channel)*1 format to obtain digital data. The MSM9562 operates at 5 V. The MSM9562 contains on one chip a band pass filter using a switched capacitor filter (SCF) and a group of circuits including frame memory, a frame synchronization circuit, and an error correction circuit. By connecting an external FM receiver and memory for temporary data storage, and microcontroller, a system for obtaining digital data can easily be constructed. The FM multiplex demodulation ICs, the MSM9500-series devices, are configured with minimum functions; so they will, by changing the software of the external microcontroller, be able to respond flexibly to the many FM multiplex broadcast services that are going to come about in the future. The MSM9562 is best suited to radios and information processing devices that support DARC FM multiplex broadcasting. It is also best suited to car radios and car navigation systems. *1 DARC is a registered trademark of NHK Engineering Services. Note that a contract needs to be made with NHK Engineering Service if a manufacturer produces/ sells electronic equipment utilizing the DARC technology.
